Title: Collection and transport system for domestic refuse - uses containers for separate reception of waste and useful materials in at least two stowage compartments
Inventor: SCHILLER ROLF DIPL ING
IPC: B65F3/02
Filed: 1990-10-20
Abstract: One measuring unit at least is provided for the determination and analysis of the refuse concerning its wt. and/or its vol. and/or its specific material characteristics and/or its purity concerning foreign material at the refuse wagon and/or at the refuse container which determines at least one of the specific characteristics of the refuse and converts this in to measurement variable. The latter effects or signals an assignment of the refuse or a fraction of it to a determined stowage compartment of the refuse vehicle. The refuse vehicle has ancillary means such as markings, magnets, sensors or similar for identifying the material characteristics of the refuse and/or the refuse vol. The refuse or the refuse fractions can be emptied in one or more intermediate containers or at least one intermediate floor of the refuse vehicle. The intermediate container or floor have measuring units for determining vol. and/or wt. or other characteristic refuse properties, and the measurement data determines or signals the assignment of the refuse in the stowage spaces in the refuse containers. USE/ADVANTAGE - Saves material of value from household refuse. Facilitates efficient recycling with identification and analysis of refuse. Allows cost factor to be better determined.

Title: Flame burn condition evaluator for IC engine - uses optic monitoring of flame with separate wavelength metering
Inventor: SOHMA KENICHI
IPC: G01M15/10
Filed: 1990-12-28
Abstract: The engine has an optic insert into the monitoring cylinder with the light from the ignition ducted along a fibre optic and split into at least two paths.

Patent DE-4117838-A1 (DE)
Inventor: SCHATZ JUERGEN
IPC: F03D1/04
Filed: 1991-05-29
Abstract: Proposed is a process and an installation for producing useable energy from parallel flows. It comprises a flow module with at least one inlet aperture (28) and one outlet aperture (10) for producing a whirl potential, and a turbine (14) aligned with the direction of flow of the whirl potential. The flow module comprises an outer hollow unit (3) which consists of a large number of shutters (4) and which is fitted on both sides with covering plates (11, 12), in one of which is provided the outlet aperture (10), and an inner hollow unit (9) arranged concentrically with the outer one. The dynamic pressure acting on the outer unit opens some of the moveable shutters while closing others, thus creating a rotating current. The rotating current is accelerated tangentially into the inner hollow unit and forms a twisting current; this is directed outwards by the underpressure at the outlet aperture, and after traversing the outlet aperture is transformed by the shearing forces in the parallel flow into a whirl potential. A partition (5) in the outer hollow unit divides the rotating current into a primary and secondary substream and has a cross-flow aperture (8) leading into the inner hollow unit. The developing whirl potential draws a volume flow from the secondary substream and/or from outside through the cross-flow aperture; a turbine is situated in the area of flow of the whirl potential. In addition, whirl-producing elements (16) are arranged in the area of the secondary substream and transform that substream into a multitude of whirls, which are incorporated into the whirl potential. The whirl potential coil thus generated creates an intensifying flow field.

Abstract: Analyser for automatically analysing body fluids for a plurality of different analytes (parameters). An analysis apparatus has reaction vessels (8) which are conveyed on the apparatus to various processing stations (10 to 16). The system also includes liquid reagents which are kept ready in reagent vessels (9) on the apparatus and whose contents are adequate for a multiplicity of analyses. In order to achieve a high degree of analytical accuracy with reduced probability of operating errors and without a substantial increase in the total system costs, a calibrator is kept available ready-for-use in liquid form in a calibrator station (17) of the analysis apparatus, the calibration is initiated for the various parameters independently of one another and is carried out fully automatically (i.e without human intervention). To initiate the calibration for a parameter, a specifically predetermined calibration initiation cycle is performed in which at least one calibration influencing variable which is inherent in the system is sampled in each case, logically combined with a specifically defined control value for the particular parameter and the decision on the initiation of the calibration is taken automatically having regard to the logical combination. <IMAGE>

Title: Wheel spanner for doubling wheel-nut releasing torque - has foldaway extension on handle which only operates when releasing wheel nut
IPC: B60B29/00
Filed: 1991-09-17
Abstract: The wheel spanner (1) has a shaft extension (3) fixed to the handle (2) by a rivet (4). The body of the extension is "U" or "L" shaped.
